Filed June 19. 1926 1 I INVENTOR z BY 660/76 12 a/gggm ATTORN Y8 Patented Jan. 28, 1930 UNITED STATES PATENT OFFICE GEORGE 1. WIGGINTON, OF KALAMAZOO, MICHIGAN, ASSIGNOR, BY M'ESNE ASSIGN- MENTS, TO REMINGTON RAND INQ, OF NEW YORK, N. Y., A CORPORATION OLE DELA- WARE BINDER Application filed June 19,

My improved binder is especially designed for the binding of sheets as permanent records, for example, official records such as State and county; particularly, the binding of sheets which it is desired to manipulate independently until ready for permanent bind- 11w.

The objects of the invention are to provide an improved binder which is well adapted for the purpose and one in which the sheets are permanently held, at the same time permitting the removal or changing of the covers as occasion may require.

Objects relating to details and economies of construction and operation of my invention will definitely appear from the detailed description to follow.

The invention is clearly defined and pointed out in the claim.

A structure which is a preferred embodiment of my invention is illustrated in the accompanying drawing, forming a part of this application, in which:

Fig. 1 is a perspective View of a completely bound book embodying the features of my invention.

Fig. 2 is a fragmentary sectional view on a line corresponding to line 22 of Fig.1.

Fig. 3 is a fragmentary sectional view on a line corresponding to line 33 of Fig. 1.

Fig. 41 is a fragmentary plan view of the sheet body bound together as a unit.

Fig. 5 is a perspective View of a pair of the fastener members by means of which the cover is attached to the sheet body.

Fig. 6 is a fragmentary perspective view showing details of the means for attaching the covers to the sheet body.

Fig. 7 is a detail view on a line corresponding to line 77 of Fig. 3.

In the drawing similar reference characters refer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Referring to the drawing, the sheets 1 are provided with holes 2 to receive the bind ng osts, and in the embodiment illustrated, with .ioles 3 to receive the sheet engaging posts 4.

The posts 4 are carried by binding bars 5 1926. Serial No. 117,071.

which are arranged in coacting pairs, the posts carried by these bars being in non-aligning relation, they are of such length as to overlap in the sheet body.

The binding posts 6 are arranged in coacting telescoping pairs, these binding posts having flat heads 7 engaging the outer sides of the binding bars, the binding bars having holes 8 therein aligned with the holes 2 in the sheets.

In the embodiment illustrated, the binding posts are clamped together by clamping mem bers ,9 interposed in the sheet body and having opposed tongues 10 adapted to clamp the binding posts together with a clutching engagement, this device being that shown in the patent to Newman, No. 1,559,? 62, dated November 3, 1925, the device being actuated by the pressure of the sheets and constituting a permanent binding means, that is, the binding cannot be disengaged without destroying or mutilating the sheets on the binding means.

The covers 11 are provided with binding flaps 12 hinged to the covers at 13, the binding flaps being provided with holes 14 registering with holes 15 in the binding bars 5, when the binding flaps are superimposed upon the binding bars, as shown.

The binding bars are secured by means of bendable fasteners 16 which have laterally turned inner ends 17 disposed between the sheet body and the binding bars so that with the fastener members projecting through the holes 15 in pairs, the ends 18 are folded and clamped down upon the binding flaps, thereby securing the covers to the bound body of sheets.

The covers may be changed or removed as occasion requires, these fastener members be ing capable of being bent to permit this.

My improved binder is especially designed by me for such uses as ofiicial records, State, county and the like, where it is required that the sheets constituting the record be perma nently bound together as a book as distinguished from retaining the loose sheet binding. Such records are frequently subjected to a great deal of rough handling and the covers soon become worn, particularly where the volumes are large as is often the case.

My improvements permit the convenient removal of the covers as occasion may require.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:

A binder assembly comprising front and back covers, binding flaps hinged to the covers adjacent the edge and on the inner faces thereof, a pile of sheets having their marginal portions disposed between the flaps, binding bars interposed between the flaps and the sheets, a plurality of holes extending through the sheets and disposed along the marginal portions thereof, binding posts projecting from the binding bars into the certain holes of the sheets, said binding posts being disposed in alternate spaced overlapping relation, a securing post projecting through one of the holes in said sheets and through said bars, means for interconnecting the securing posts and sheets and bars, whereby the binding bars and sheets are assembled as a unit, said binding flaps and binding bars being formed with aligned apertures, and bendable U-shaped fasteners extending through said apertures and having one portion disposed between the sheets and the binding bar and another portion dis osed between the opposite surface of the bin ing bar and the adjacent cover.

In witness whereof I have hereunto set my hand.

GEORGE P. WIGGINTON.
